Bushnell has a two year manufacture warranty. I have 7 of the 2009 model Bushnell Trophy Trail cameras. No problems. Moultrie has a one year manufacture warranty. I have 3 of the D55-IR and 2 of the M100. These have given excellent service. A couple of things that I do not like about Moultrie cameras are: 1)field of view is narrower in the video than in the picture. Moultrie said this is how it uploads. When set to video they take a picture first, then the video. What you capture in the picture may be missed in the video due to delay. 2)Night video is limited to 10 seconds which is useless. Emailing Moultrie when I bought the D55-IR, they said they had no intention of up grading the software or making longer night video in future cameras as it would be harder on batteries.
As a suggestion, whatever brand of camera you decide on I would: purchase a camera that uses "AA" batteries because: 1)the cameras are smaller and easier to conceal, 2)if using in a cold weather area, one can use Lithium Ultimate batteries which test at 1.79 to 1.83 volt. These are high voltage batteries. This is the reason they last longer and are better suited for cold weather. Good luck in your choice.
